Cambridge is a city that is taking a stand against current immigration policy:

In 1985, the Cambridge City Council passed an order declaring Cambridge a “Sanctuary City.” The order required that — when legally possible — city employees not assist in the investigations of the citizenship status of any Cambridge residents. It also barred city employees from will disseminating information regarding the citizenship of residents.

Essentially, Cambridge recognizes the harmful economic effects, along with the intrusion into the lives of its citizens, federal immigration policies cause. They are to be applauded.
